From the manufacturer
This Toolcraft P51+ Polished DLC BCG is made with a carpenter 158 bolt with a full-auto profile, designed to be used in AR-15 & M-16 style rifles. Bolt is magnetic particle inspected (MPI) for a uniform quality and operational reliability. Time for the good stuff. When we talk about benefits, P51+ leads that pack. These bar-setting benefits are what make P51+ the crowd favorite when it comes to DLC coatings.
